DOI: 10.1007/s42243-019-00245-7
Abstract: To reduce the volatilization of the volatile-containing slags and obtain accurate measurement results of slag performance, the volatility degree and deviation mechanism must be determined. Non-isothermal thermogravimetric analysis at different heating rates was used to… read more here.

DOI: 10.1039/d2ra06707b
Abstract: P2O5–SiO2–Na2O–CaO glasses are promising therapeutic ion-releasing materials. Herein, we investigated the state of silicon (Si) in P2O5–SiO2–Na2O–CaO glass using a model with a composition of 55.0P2O5–21.3SiO2–23.7Na2O (mol%), incorporating a six-fold-coordinated silicon structure ([6]Si). The model… read more here.
